Применение HIVE на примере анализа лога

Для примера беру лог squid:

Копируем его в HDFS:

$ hdfs dfs -put /tmp/access.log /user/hive/

Переключаемся в консоль Hive (не забываем, что подключаться надо через ZooKeeper!):

$ beeline -u "jdbc:hive2://master1.hadoop.stage.int.nic.ru:2181,master2.hadoop.stage.int.nic.ru:2181/; serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2" -n hive
